An adaptation on the classic donkey punch. So, you have a girl well and truly bent over. Whilst fucking her (anal is completely out of the question for the manoeuvre) you aquire her attention, as she turns her head round you duck and dive into her blind spot. Hook to the head. Bang. Out. Then cum on her twitching back, that's the reward.

Mark: I've been donkey punching so much lately, it's like the new missionary

Nick: Yeah I had that problem, now I get my kicks from blind spotting. It's an all round more fulfilling assault.

The Urban Dictionary Mug

When a situation or an image can be interpreted in two different ways, but you can only see one of the interpretations. You have a blindspot to the second interpretation. Often used when referring to people seeing the wrong interpretation.
